These shoes are incredible, Velcro makes them super easy to take on and off, and the comfort is unmatched. I did put my own 3rd party insoles in these, however I've put the same insoles in other shoes and they just don't quite feel the same.
I could go on and on about why I like these, but to shorten this review, basically everything they are advertised to do, they do it perfectly.
I use these as riding boots for my motorcycle, I have previous metatarsal injuries and wanted to protect against any future mishaps.
Now for the critical part, they look goofy, there's no way to sugar coat it, I have worn these daily, probably 300 days per year for 3 years and the only comments I get are on the Met guard. So I cut them off, and re-attached them higher up to the top strap. This eliminated one issue of un-necessary overlap with the steel toe, and keeps them held down tighter to the boot for a cleaner look which is the other issue... the goofy look.
Now they still aren't winning any beauty pageants, but this was a major improvement for me. If you're looking for a boot like this, but don't like the look, I would recommend Product:6300VTMG for the built-in met guard, also more ankle protection.
